Scratching sound when turning left

[Tatyanarae]

Initially this started when turning left only and decelerating. Now, regardless of deceleration at low speeds, the screeching sound is on.
Sometimes it’s there. The wheel is not turning to the left by most of the time it’s on the wheel is turned to the left. The sound is sounds like it’s coming from the back passenger wheel. Sounds like something is scratching. Attaching the back passenger tire disc picture and the front just for reference. I think it’s a rock stuck somewhere probably in the brake pad?
Everything else I’ve read it says that the rock in the tire but I’m not sure anybody had this happen?
I have model S 2016 P90D

Also forgot to mention, I hit a pothole right before the started had to replace the tire

Brake pads probably stuck. Common problem, how old are they?

 

[Tatyanarae]

pretty sure original

Sometimes slamming on the brakes when not in traffic will free them up.

 

[Tatyanarae]

Tried that. No luck

Any brake mechanic can lube the slides, unfortunately it's tedious and not cheap. Part of the regular maintenance, hopefully it stops the noise.

Thank you

Wait why is this tedious and not cheap? For a shop with a lift, it's a 0.5 hr job with a dollar worth of grease.

But there aren't any slides on the Monoblock Brembo's in the '16. The lube points are the pins, and the side of the pads.

OP, perhaps it's time to just throw on new pads? They're cheap, and any brake shop can do it. Nothing special about Tesla brakes.

Thank you both for your help. I guess I was wondering if this could be some thing else or by the look of these pictures could you tell that it’s a brake pad?

Looking at your image, it certainly seems something is preventing pad contact with the rotor in a couple areas. I think it's worthwhile to replace the pads and clean the rotors.

Awesome thank you so much for your help!
